Wearer of many hats
I'm playing Devil's advocate to make a point. Nothing personal here.
Yes. Even if we fail, at least we'll know we did our best instead of standing by.
My emphasis - these are all assumptions that aren't necessarily true.
My green options for transport are a vehicle I can't afford that does more damage to the planet and is less fuel efficient than the one I am currently driving, or a vehicle I can't afford that can't hold enough charge to get me to work and back and pushes the energy problem back to the power station...... and before you say it, no I am not going to cycle a 90 mile round trip to work every day..... and the bus runs once a day, and arrives two hours after I am due to arrive at work and leaves two hours before I am supposed to leave work, and costs more that using my car.
The majority of environmental solutions, like water usage reduction" means that my shower duration is too short or my bath is too shallow to be a pleasant experience and don't have enough water to flush my effluent away, etc. All of these things are personal compromises that negatively impact the individual and have negligible impact in the grand scheme of things.
